A virus takes 13 days to double its original population (A = 2A0). How long will it take to triple its population? Round to
the nearest tenth.
Answers
Answer:
20.6
Step-by-step explanation:
The exponential function to solve the problem.
A = [tex]A_0[/tex] [tex]e^{rt}[/tex]
A = population in time t.
[tex]A_0[/tex] = Initial population.
r = growth rate.
t = time
The number of days taken to triple the population is 20.7 days.
What is a function?
A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The exponential function to solve the problem.
A = [tex]A_0[/tex] [tex]e^{rt}[/tex]
A = population in time t.
[tex]A_0[/tex] = Initial population.
r = growth rate.
t = time
Now,
A = 2[tex]A_0[/tex]
t = 13
A = [tex]A_0[/tex] [tex]e^{rt}[/tex]
[tex]2A_0[/tex] = [tex]A_0e^{13r}[/tex]
2 = [tex]e^{13r}[/tex]
Taking logs on both sides.
log 2 = 13r log e
0.30 = 13r
r = 0.30/13
r = 0.023
Now,
A = 3[tex]A_0[/tex]
A = [tex]A_0[/tex] [tex]e^{rt}[/tex]
3 = [tex]e^{rt}[/tex]
log 3 = rt
0.48 = 0.023t
t = 0.48/0.023
t = 20.7 days.
Thus,
The number of days taken to triple the population is 20.7 days.

The sum of three consecutive numbers is 84. What is the largest of these numbers? (1 point)

WILL GIVE BRAINLEST!!!!!!
Answers
Answer:
29
Step-by-step explanation:
First, we have to find three numbers out of the four that add up to 84. But, it has to be in order because the question says consecutive numbers. In case you don’t know, consecutive numbers are numbers that increase at the same rate. In this problem, the numbers increase by one. I first did 26+27+28, which equaled 81. I have to get to 84 though. So, I did 27+28+29, which equaled 84. I did it correctly because 27, 28, and 29 are consecutive number, since they go inorder, and I added them up to 84. But the question is asking which of the three is the largest number. So, out of 27, 28, and 29, 29 is the largest number.
Hope this helps and answers your question! :)

An ice cream cone with a diameter of 2 inches and a height of 3.5 inches is filled with ice cream and more ice cream on top in the form of a hemisphere with the radius equal to the radius of the cone. Compute the total volume of ice cream it contains.
Answers
Answer:
11pi/6 in^3 or
5.760 in^3 to the nearest thousandth.
Step-by-step explanation:
Volume of ice cream = volume of the cone + volume of the hemisphere
= 1/3 pi r^2 h + 1/2 * 4/3 pi r^3
= 1/3 pi 1^2 * 3.5 + 2/3 pi 1^3 (as the radius = 1/2 * diameter)
= (7/6 + 2/3) pi
= 11pi/6 in^3.

What is the area in square feet?
Answers
Answer:
426 square feet
Step-by-step explanation:
First, find the angle of each shape separately.
Area of a triangle = 1/2 base times height
1/2(9x8)
1/2(72) = 36
Area of a rectangle = base times height.
26 x 15 = 390
Now, add the numbers together to get the total area. 390+36=426
Answer:
426 square feet
Step-by-step explanation:
-First find the area of the rectangle:
26 x 15 = 390
-Next, find the area of the triangle on top:
9 x 8/2 = 36
-Finally, add the two to get the full area of the figure:
390 + 36 = 426
Answer: 426 square feet

Answer:
[tex]s = 1[/tex]
Step-by-step explanation:
Given
[tex]s - \frac{1}{2} = \frac{1}{2}[/tex]
Required
Solve for s
[tex]s - \frac{1}{2} = \frac{1}{2}[/tex]
Add [tex]\frac{1}{2}[/tex] to both sides
[tex]s - \frac{1}{2} + \frac{1}{2} = \frac{1}{2} + \frac{1}{2}[/tex]
Take LCM
[tex]s + \frac{-1+1}{2} = \frac{1+1}{2}[/tex]
[tex]s + \frac{0}{2} = \frac{2}{2}[/tex]
[tex]s +0 = 1[/tex]
